My old 2 Camera setup was a Canon 20D + Rebel XT (for backup and second shooter), now it is.....
a Canon 50D + my 20D !!!!!!!!!!
I went looking for a 40D, and ordered a refurb one - only to have it arrive DOA ( I called it my Canon 40DOA !) I sent it back and they did not have another to exchange it with...a little web searching and soul searching and bank checking, etc....and I have a shiny new 50D !!
I am happy that both bodies are now the same - it is clumsy when you are shooting 2 bodies (swapping back and forth), and they are different (I had some challenges recently...)

..now to sell some stuff to pay for it....the Canon Rebel XT is already gone, I have an auction up on e-bay for a Nikon 43-86mm, another post here for a 28mm....I think it is now time to say good bye to my Pentax 6x7 Kit....
